CDFW was informed by the Tahoe Regional Planning Agency (TRPA) that divers monitoring for aquatic invasive species in Lake Tahoe detected invasive New Zealand mudsnails (Potamopyrgus antipodarum) in areas off the South Shore of Lake Tahoe. New Zealand mudsnail samples were subsequently positively identified by experts within CDFW and an outside genetics lab. This is the first time the species has been detected in Lake Tahoe.
